<p>well, there's two ways of representing that; perf.rlo went with the approach of having all the files loaded into memory and then we draw graphs etc -- you could probably use a lot of the same infrastructure if you wanted to</p>

<p>Generally I would try and start off with asking questions -- that is, what are you interested in knowing?</p>
<p>I think for playground at least for me I would be interested in:<br>
 - What is the percentage of users for stable/beta/nightly?<br>
 - How many uses of compile debug vs. release?<br>
 - How many uses of the non-standard LLVM/MIR/etc?<br>
 - What crates are most used?</p>
<p>Maybe some more</p>

<p>That's a similar format to what perf uses, yeah -- if you <code>python -m json.tool</code> one of the data files in rustc-timing/times then you'll quickly see the exact format. However, I'd maybe go with a different one for your purposes</p>

<p>Anyway -- I need to run for a bit but will be back later; I'd probably get a solid idea of what data you want to collect and maybe just start with collecting it (the format you proposed seems pretty good, can be relatively easily put into some other format if necessary).</p>

<p>For example, an unnamed compiler developer (let's call them "e. b.") said the playground should switch the default assembly output format "because everyone changes that setting".</p>
<p>because I haven't already been collecting that usage data, I can't make any decisions now. at best I can start logging that and then wait until "enough" data has been collected</p>

<p>I'm <em>far</em> from being an expert on security tbh — but we're effectively already in the worst case scenario of executing random code :) so I'm not immediately seeing how this makes things obviously worse. I don't know if it may be interesting to ensure the playground server can blacklist some servers if need be ? And that targets can disallow being loaded (maybe this can happen if a site changes owners) but I assume <code>fetch</code> would by default do so in the browser if CORS is disallowed by the remote server (that would require making the requests to get the code client-side, whereas I think the GH support today is done by the server) — similarly maybe if some day the target server disallows requests, we can automatically add it the blacklist so that we don't bother it anymore.  (that was very ramby sorry)</p>

<p>I assume the actual request happens from the server? so this would effectively be some form of open proxy, albeit one where the reply does not get rendered by the browser. hm.</p>

<p>The playground currently is both client-side and server-side for gists. The Gist API requires authentication, which is done server side. The client makes a request to the backend. Yes, this means that the playground can be used to circumvent GitHubs API and once someone abuses that, it's basically over.</p>
